排土场是矿区水土流失的重点区域,该文通过对马钢姑山矿钟山排土场和南山矿凹山排土场的现状、水土流失治理措施及治理后的水土保持效益指标进行分析,明确了冶金矿山排土场水土流失治理应使剥离、排土、治理在时空上紧密结合,采取工程措施和植物措施相结合、工程措施先行、植物措施立体防护的治理方式,其中工程措施应以边坡防护、拦挡、排水、土地整治为主,植物措施应以当地乡土树种及试种成功的品种为主,并适当考虑景观效益和经济效益。
The dumping area is the key area of soil and water loss in the mining area. By analyzing the current situation of the Gushan Dumping Area of Gushan Mine and the valley reclamation site of Nanshan Mine in Gansu, the control measures of soil and water loss and the indicators of soil and water conservation benefit after the treatment, The treatment of soil and water loss in the dumps of metallurgical mines should be closely integrated with stripping, draining and treatment in time and space. The combination of engineering measures and plant measures shall be taken firstly, and the engineering measures should be taken first and the measures of three-dimensional protection of plant measures should be adopted. Slope protection, blockade, drainage and land remediation. Plant measures should be based on local native tree species and varieties tested for success, with appropriate consideration of landscape and economic benefits.
